Subject [jira] Commented: (MYFACES-213) commandLink does not work in dataList
Date Tue, 26 Apr 2005 19:23:27 GMT
     [ http://issues.apache.org/jira/browse/MYFACES-213?page=comments#action_63826 ]
     
Rob Decker commented on MYFACES-213:
------------------------------------

Try moving the value attribute out of the commandLink and make it an outputText child instead.
I think the bug is that when a commandLink has attributes other than id and action the action
doesn't trigger.

> I've been trying to get a simple commandLink to work in a dataList. I have the dataList
bound to a UIData component (binding="#{categoryAdmin.ancestorTree}") on the backing bean.
It properly displays links. However, when i select the link it fails to call the appropriate
action method (action="#{categoryAdmin.ancestor}")and returns back to the page. No error meassages
are written to the screen or logs.
> Things i have tried with no success are:
> - placing my backing bean in session rather than request
> - placed <h:messages/> on the jsp to see any error messages (none appear)
> - Debugged the phases in the LifeCycleImpl. It hits all the full LifeCycle phases (restoreView,applyRequestValues,processValidations,updateModelValues,invokeApplication).
However, i am not able to determine what is really happening in these phases to result in
the outcome.
> - used h:commandLink and x:commandLink (both with session and request backing bean)
> - set a breakpoint in my action method (public String ancestor(){...}) method and it
never gets called.
> Following is my page code. I provided the whole page to give context in case there are
other conflicts that may be taking place. I'd be happy to provide a small app to reproduce
this if my explanation is not enough.
